A new minute-long trailer for the third season of The Walking Dead suggests Rick and the other survivors have been on the road for some time following their escape from the Greene farm in the Season 2 finale.

AMC has released 17 cast portraits for the third season of The Walking Dead featuring everyone from Danai Gurira as the fan-favorite Michonne to Chandler Riggs as Carl Grimes to Michael Rooker as the returning Merle Dixon.

A poster has debuted featuring Andrew Lincoln running toward Hershel's farm, the central setting for much of the second season of the AMC drama. The Walking Dead returns with a 90-minute premiere on Oct. 16.
